Possible causes:

Possible cause:
Your printer may have recently installed a firmware update that blocks third-party compatible chips.

Solutions:

• Check whether automatic firmware updates are enabled.
• Disable firmware auto-updates to prevent future issues.
• Contact customer support to confirm whether an updated chip version is required.

Possible causes:

• Toner powder is unevenly distributed.
• Minor vibration during shipping.
• Residual toner or debris inside the printer.

Solutions:

• Gently shake the toner cartridge horizontally 5–6 times.
• Run the printer’s built-in cleaning function.
• Check whether all protective strips have been removed.
• Clean any loose toner inside the printer and reinstall the cartridge.

Explanation:
Compatible cartridges provide excellent value for everyday printing. However, slight differences in text sharpness or color accuracy may occur compared to original OEM cartridges, especially for photo or high-precision printing.

Solutions:

• Select “High Quality” print mode in printer settings.
• Run printer calibration or color adjustment.
• Use the correct paper type settings.
• Print regularly to prevent ink drying.

Possible causes:

• The cartridge has not been used for a long period.
• Printheads are partially clogged.
• Storage conditions are too hot or dry.

Solutions:

• Run the printer’s printhead cleaning function 1–2 times.
• Print a test page to check color performance.
• Print at least once per week to maintain ink flow.
• Store unused cartridges in a sealed, cool environment away from sunlight.

Possible causes:

• Protective covers or sealing tape were not fully removed.
• Dirty or poor chip contact.
• Incorrect installation procedure.

Solutions:

• Verify that all protective materials have been completely removed.
• Gently clean the chip contacts with a dry, lint-free cloth.
• Reinstall the cartridge until it clicks securely into place.
• Press “Continue,” “OK,” or “Proceed” if compatibility warnings appear.

Explanation:
Page yield estimates are based on industry-standard testing at approximately 5% page coverage. Actual yield may vary depending on:

• Full-page color printing.
• Photo printing.
• Frequent printhead cleaning.
• Heavy graphics or dense text printing.

As a result, different printing habits can significantly affect cartridge lifespan.

Explanation:
Minor toner residue may occasionally occur due to vibration during shipping. This is uncommon and usually does not affect normal printing performance.

Solutions:

• Wipe away any loose toner with a tissue or dry cloth.
• Gently shake the toner cartridge before installation.
• Continue normal installation and printing.
